Two mountain climbers have died on Mount Everest, the first deaths since expeditions resumed this year.
Dutch mountaineer, 35-year-old Eric Arnold, died on his descent near the South Col on Friday night from high-altitude sickness, Kathmandu trekking leader Pasang Phurba Sherpa told reporters.
Although Arnold had oxygen supplies and support, he died before he was able to descend to a lower altitude.
Australian university lecturer Maria Strydom died on Saturday on her way down from the top.
"After reaching the summit yesterday she said she was feeling very weak and suffering from a loss of energy -- signs of altitude sickness," Phurba said.
She then succumbed to exhaustion and snow blindness, and is believed to have suffered a stroke.
